Overview

We carry a few different GPS modules here in the Adafruit shop, but none that satisfied our every desire - that's why

we designed this little GPS breakout board. We believe this is the Ultimate GPS module, so we named it that. It's got

everything you want and more:

-165 dBm sensitivity, 10 Hz updates, 66 channels

5V friendly design and only 20mA current draw

Breadboard friendly + two mounting holes

RTC battery-compatible

Built-in datalogging

PPS output on fix

Internal patch antenna + u.FL connector for external active antenna

Fix status LED

The breakout is built around the MTK3339 chipset, a no-nonsense, high-quality GPS module that can track up to 22

satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built in antenna. It can do

up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low,

only 20 mA during navigation.
